The return of the sail ship
Imagine a cargo ship that is nearly 500 feet long being powered by the wind, obviously it is not a new concept as ships used to wind powered, by they were very different then, these cargo ships are way different.
The sail will be more like a kite as it allowed to drift over 600 feet above the ship, this clearly will not totally replace the engines as they are needed for manoeuvring and for power, but when the sail is deployed during the long journey the ship can save around 20% of the fuel consumption, which is not bad at all.
